newbie advice - flux capacitor

Hi there,

Im a newbie to this forum and also to electronics. I’ve done some basic stuff many years ago, but obviously the technology has come a long way.

I’m looking to make a simple flux capacitor (from Back to the Future) sewn onto a smallish piece of fabric (about 8" square). It should be able to be turned on by a button/touch sensor. safe for kids to use is essential.

Can anyone advise me on how to go about this and what I should buy? I’ve been looking at what products to buy but am lost in a sea of possibilities.

Appreciate the help!

Cheers

Lisa
